NEW: 2021-23 Ford F150 Billet Shackle & Leaf Pack 2.5-3in Suspension Systems

ICON Vehicle Dynamics introduces complete Suspension Systems for 2021-23 Ford F150 4WD standard editions (3.5 to 4.5-inch) and Tremor edition (2.5 to 3-inch) featuring our Raptor Multi-Rate Rear Leaf Springs. To make these high performance rear leaf springs possible in non-Raptor trucks we've developed a set of billet 1" drop shackles, which are included in each of these suspension systems and also available as a stand-alone product. The rest of the components that make up these systems have been previously introduced, so let's take a closer look at the Billet Shackles themselves before moving on to the complete kits.

Billet 1 Inch Lowering Shackle Kit

Dial in your Ford F150 or F250's rear suspension height for leveling or to match suspension lift components for a lifted, level ride. These shackles yield 1" of drop in the rear suspension height. CNC machined billet aluminum construction is both great looking and durable. A factory style bonded bushing provides maintenance-free, quiet operation.

Key Features:

  • Provides 1" of rear suspension drop
  • CNC machined 6061 aircraft grade aluminum
  • Bonded bushing for maintenance-free performance and durability
  • Fits 2010 and newer Ford F150 and F250 trucks

ICON designed these billet shackles specifically to make it possible to install ICON Gen2 Raptor Multi-Rate Leaf Packs into 2021-23 F150 Standard or Tremor models. This makes them a perfect complement to our 2.5 VS Front Coilovers. If you're not yet familiar with our Gen2 Raptor Multi-Rate Leaf Pack, here are the pertinent details:

Raptor Multi-Rate Leaf Pack

Key Features:

  • 3 user-adjustable spring rates for unique vehicle setups
  • Triple military wrap front eyelet and rear half wrap for increased durability
  • Rebound leaf reduces severe axle wrap
  • Leaf separators and tip inserts reduce noise and friction while increasing ride comfort
  • Direct bolt-in to OEM spring location makes for an easy install
  • "ICON 1K" tested under rigorous off-road conditions to validate tune, performance, strength, and durability

The "Multi-Rate" feature of these rear leaf spring packs makes it possible to dial in your truck's rear spring rate/lift height to accommodate a wide range of use cases and weight ranges, from empty-bed weekend warriors to fully outfitted overlanders to tool-laden work trucks, while optimizing suspension performance, wheel travel and ride quality.

For ordering convenience we've configured a range of Complete Suspension System "Stage" Kits for 2021-23 Ford F150 and F150 Tremor, that include these Billet Shackles and the Gen2 Raptor Multi-Rate Leaf Packs, along with our Delta Joint Pro UCA's and a variety of front coilover and rear shock configurations.
